For more than two decades, the Lattice Boltzmann (LB) method has gained increasing interest as an efficient computational scheme for the numerical simulation of complex fluid problems across a broad range of scales, from fully-developed turbulence in complex geometries, to multiphase microflows, all the way down to biopolymer translocation in nanopores and lately even quantum- relativistic flows in quark-gluon plasmas and graphene. After a brief introduction to the main ideas behind the LB method, in this talk we shall illustrate a few selected applications, along with prospects for future multiscale application.
